Aim:Aim: To examine the morphometric properties of the vessels forming the Willis polygon (WP) in patients with type 2 diabetes mellitus (T2DM) and hypertension (HT) and compare them with healthy individuals.Material and Methods:Materials and Methods: Cranial computed tomographic angiography (CTA) images of 168 individuals were analyzed retrospectively. The patients included in the study were divided into four groups according to their diagnoses. Group 1 included 40 individuals with HT, group 2 included 43 individuals with T2DM, group 3 included 42 individuals with T2DM and HT, and group 4, the control group, included 43 individuals. The diameter and length measurements of the vessels forming the WP in each participant were examined in our study.Results:Results: According to the results of the Kruskal-Wallis H test, substantial significant differences were detected between the diameter of the right and left A1 substantial segment of the a. cerebri anterior (ACA), the diameter of the left A2 segment, the diameter of the right and left P1 and P2 segments of the a. cerebri posterior (ACP), and the diameter of the right and left a. communicans posterior (AComP) (p<0.05) in female patients, and substantial statistical differences were found between the diameter of the right A1 segment of the ACA, the diameter and segment length of the right and left P1 segments of the ACP, the right and left P2 diameters, and the segment length of the left AComP (p<0.05) in male patients. Vessel diameters were similar in the HT, T2DM, and HT+T2DM groups, but were smaller compared with the control group. Conclusion:Conclusion: We think that being knowledgeable about WP morphometric measurements will guide radio-anatomic evaluations and increase the level of microanatomic knowledge in surgical treatment.
